Both Paparoni and Anilaza were confident in it's chances against Kale, though that isn't much of a basis when it was proven false. It's worth noting that one of the robots part of it's formation was significant enough for Jiren to bother going after a few chapters back when SSJ Galu wasn't even on his radar, as was Nigrisshi who seemed to be part of it's formation manga-wise based on his absence in the panel of the other U3 characters getting erased, so I guess maybe in between SS3 and SSG tier or towards the low end of the latter via scaling.
